Detailed Description
The invention will be further described with reference to the accompanying drawings.
The device comprises a cylindrical initial plug 1 and a reading plug 2, as shown in fig. 1-5, bolt hole plugs 3 are arranged at the lower ends of the initial plug 1 and the reading plug 2, semicircular through hole grooves 11 parallel to the upper end face of the initial plug 1 are formed in the side ends of the initial plug 1, clamping screw holes 12 are vertically formed in positions, corresponding to the semicircular through hole grooves 11, of the initial plug 1, clamping screws 13 are arranged in the clamping screw holes 12, and conical protrusions 21 are arranged at positions, located at the circle centers, of the upper end face of the reading plug 2.
The clamping screw hole 12 is positioned at the eccentric center of the end face of the starting plug 1.
According to the invention, an initial plug 1, a reading plug 2 and a keyhole plug 3 with matched diameters are processed according to the keyhole aperture, and when the device is used for measuring, firstly, obstacles among the keyhole are removed, the initial end of a steel tape 4 is clamped in a semicircular through hole groove 11 in the initial plug 1, and the circle center of the end part of a clamping screw 13 is aligned with the 0 scale of the steel tape 4; the initial plug 1 and the reading plug 2 are respectively placed in two bolt holes, the reading end of the steel tape 4 is tensioned, the conical protrusion 21 in the middle of the protrusion on the upper part of the plug Ji Doushu is scaled, the accurate reading is performed, when the bolt hole distance is overlarge and the cooperation of a chest expander is needed, the chest expander is connected with the reading end of the steel tape 4, the specified pulling force is pulled, and the scale of the steel tape 4 is matched with the conical protrusion 21 in the middle of the protrusion on the upper part of the Ji Doushu plug 2, so that the accurate reading is performed; after reading, whether the initial end of the steel tape 4 in the initial plug 1 is loose or not, if not, a measurement result can be obtained, and if so, the operation is repeated until the steel tape 4 in the initial plug 1 is not loose after reading
The main control point of the device is that a plug hole plug 3, a starting plug 1 and a reading plug 2 which are matched with the plug hole diameter are selected, so that the plugs can not shake after being naturally placed in the plug holes; before measurement, checking whether the plugs are damaged or not, and removing obstacles among the bolt holes; the initial end of the steel tape 4 in the initial plug 1 is clamped and aligned with the 0 scale, and whether the steel tape in the plug 1 is loose or not is checked after measurement; by the device, the problem of measuring accuracy of the bolt hole spacing of any same plane can be solved.
